Application July 31, 1947, Serial No. 765,085

This invention relates to agricultural implements and more specifically to attachments for turning plows and similar devices, the usefulness of said invention being manifest in the aid it renders in the eradication of useless and/ or parasitic vegetation.

The principal object of this invention is to provide a revolving disintegrator for separating the soil from the vegetation, a novelty of its construction being its tapered design which adapts it to irregular terrain.

Another object of the invention is to provide a flexibility of movement for the various parts of the device in thei mutual relationship.

Still another object of the invention is to provide means for attachment to the beam of a turning plow, said means for attachment permitting rigid angular relationship between the plow share and the revolving disintegrator.

With the foregoing objects as paramount, the invention has reference to certain features of construction and performance which will become increasingly apparent as the description proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 is a perspective view of the invention illustrating its position in relation to a turning plow, the latter being shown fragmentarily.

Figure 2 is a fragmentary perspective view of the invention, illustrating in greater detail the means for attaching it to the beam of a turning plow.

Figure 3 is a fragmentary rear elevational view of a modified form of the invention, illustrating the means provided to permit certain convolutions of the spiral to obtain lateral movement in relation to other convolutions, and showing a gradual reduction in the diameter of the spiral.

Figure 4 is a fragmentary sectional view of the spiral illustrating in greater detail the construction shown in Figure 3, and

Figure 5 is a rear elevational view 0f the plurality of rings or hoops, forming the disintegrator, illustrating a means for rigid axial support for the smaller end, and the lugs attached thereto as means for obtaining traction.

Continuing with a more detailed description of the drawing, and referring particularly to Figures 1 and 2, reference numeral l0 denotes the beam of a plow frame, having :a plow share H attached thereto below an angular bend thereof. It is not intended herein to limit the adaptations of the invention to use in combination with or attachment to a turning plow, as the design and con truction of the invention is such as to be of 2 Claims. (Cl. 97-6) great practical use in operation with other types of implements and/ or machines.

Referring now to Figures 1 and 5, it will be noted that the disintegrating unit of the invention comprises a plurality of hoops or rings l2,

maintained in spaced proximity by a series of laterally disposed straps I3. In this design the outer ring of the plurality of rings I2 is of lesser diameter in scope than those remaining. A plurality of short straps M are rigidly affixed to the outer ring and to the ring of nearest proximity thereto. These straps l4 serve the dual purpose of maintaining the two outer rings in spaced relationship, as well as providing a means for affording traction to cause the disintegrating unit to revolve as it is propelled over the earth by the implement to which it may be attached. The rings l2 nearest in relation to a propelling implement when ready for operation, are rigidly affixed in spaced relationship at alternate intervals, as shown in Figure 5. At other alternate intervals and on alternate rings, a means is provided for permitting certain portions of saidrings to be capable of lateral movement in their mutual relationship, this movement, or vibration, tending to release sod from the roots of useless or undesirable vegetation. A pin [5, affixed at intervals to the rings l2, extends outwardly through elongated openings IB through the'straps [3, thereby permitting the lateral movement of said rings l2, as hereinbefore described.

Axial support of the disintegrating unit is accomplished by means of a collar Ilia which fits circumferentially around an axle I! of that portion of the invention used as a means for support of said unit and as a method of attachment to the propelling implement. Diagonally disposed spokes |8 affixed to the collar Isa, radiate outwardly to and are affixed to the outer ring of the disintegrating unit, thus providing a, semirigid means for sustaining said unit in concentric relation to the axle H. An additional collar i9 is made to encircle the end of the axle ll to act as a means for maintaining the collar l6 in its proper operating position.

A similar collar 20 is slidably placed around the axle I! and held in place by another collar 2|, the latter having a set screw therein for rigid attachment to the axle 11, as is also the case with the collar l9 hereinbefore mentioned.

The axle l'l' extends through a combination collar and clevis 22, having a collar 23 placed on each side of said clevis 22; these being similar in construction and means for attachment as in the case of the collars l9 and. 2!. a shaft 24 extends transversely through the clevis 22 and is held in its desired position by means of a collar 25, similar in construction and design to the collars l9, 2| and 23 as hereinbefore described.

Attachment of the shaft 24 to the beam I of a plow is accomplished satisfactorily by means of a pair of opposing flat plates 26, which maintain a downwardly extending position of said shaft 24 in rigid juxtapositioned relationship with the side'of said beam t0, the downwardly extending position of the shaft 24 in fairly rigid placement.

A short lug 28 is affixed subjacent the slidable collar 20, said lug 28 having a hole therethrough to receive a bolt 29 which is ameansior joining said lug 28 with a flat extendable bar 30 extending angularly toward the beam ll! of a plow.

A pair of opposing flat plates 31 are-heldin place along the beam ID by means of bolts 32, as

illustrated in Figures 1 and 2. A link 33, extending from the side of the flat bar 30, encircles one of the b0lts'32, thereby acting asa connector between the -flat bar '3Uan'd' the beam l ll,'throiigh fixed relationship with"th'e plates 3I. The angular position of the disintegrating unit in relation to the blow share I l 'is"obtained"by longitudinal aldjus fininflof thdoppdsingplates 3! along the beam'l'll. Another nieans'for such adjustment ay he" noted b yiference wrigurez, which '11- lustrates in en1a'rgd 'de tailithe plural membership of "the flat hart. A plurality of' news an through said bar '30 is providedto receive bolts 35, thus providing means f or shortening or lengthening the" space defined between the extremities within the disintegrating unit forward: of :the center Oii #22 4 1? in l Q teed, ew predetiilg a w rd m eme to v -isl niti rr e. to m n te withd aw PQ ihl pp hemplementtowhichitis attaeh ech Other slightadjustments may be necessary in the case of exces- I si y eta q ,g N

A modified form of thedis integrating unit illustrated in e 3am t. in w ch s aunit'i designed and constructed as a tapering spiral having a series gitconvolutions 36 otcircular crossfsection. Certain ones of these convolutionsare capable of movement inrelation-to adjacent convolutlons as hereinbefore described in reference to the rings illustrated in Figure 5. This relative movement tends to release the sod from the roots of vegetation by agitation in order that 5 the roots may be more quickly disposed upon the freshly turned earth.

Axial support of this modification is obtained by lateral extensions of the spiral to a concentric collar 31 capable of circumferential placement upon the axle I! as hereinbefore described in reference to the collar l6.

Manifestly, the construction as shown and described is capable of some modification and such modificationas'may be construed to fall within '15 thescope and meaning of the appended claims is also considered to be within the spirit and intent ofthe invention.

What is claimed is: -1.'Aweed eradicating attachment for a plow comprising a sod disintegrating cage consisting of a plurality of rings of equal diameter-and an outer ring of less diameter than'the'firstmentiondrings; a'series of lateralstr'ips spaced circumferentially about said cage and connected stationarilywith the two'outer' rings ofsaid cage, means connectingth'e inner or said rings tosaid straps for limited lateral displacement with respect to one another and means -for'attaching said cage "to said plow.
